Application lecl March 9,

To @ZZ fie/ima if may Gonne/riz:

Be it known that l, lionis Sol-renier, a citizen oi vthe llnited fltatcs, residing` at Philadelphia, in the county ot' Philadelphia and n tion which may be. collapsed into a very small space and be contained in a casing or holder ot relatively small dimensions, so that. .it will oci'upy little space in a pocket of a person rarryinfg the saine when the Cup is not in use, and so that it may be readily available lor use when desired.

'lf he invention aims to provide a cup which will gradually and automatically assume ai` open condition ttor use while being` reiioved Yfrom its carrying case, and which will be automatically returned to its eollapsed condition by co-operition with its carrying` case when .it is gently pushed hack into the same.

lilith the foregoing; objects in view, the invention consists in the novel construction, conilfeination and arraireenient'ol' parts hereinafter described and Claimed.

ln the accompaiiyine` drawinus, ing my invention:

Figure l is a side riew et a cup, embodyine my invention.

Figure is a bottom illustratview the i'eof,

Figure 3 is a vertical section thereof. Figure l a vertif'al section through a easing` tor the rup. showin;- the cup in eollapsed condition therein.

lFigure 5 is a sectional view ot the casino' with its corer removed and showing' the cup partly inserted in or partly withdrawn theretrom.

Figure o is a side view of a modification of the cup.

Figure T is a sectional view ot a modification et the casinotor the cup shown in Fig. 6, showing` the cup eollapsed therein.

Reiterring` to Figs. l to 5, inclusive, oi2 the drawings. 2 designates a cup which may be .termed ot rubber or any other suitable, water-proof, collapsible material. The Cup 2 may be of any appropriate shape and size Speceetion of Letters Patent.

for its intended purpose, and, as herein illustrated. it has a tapered or conical form.

rlhe Cup 9 is enclosed within a cage coinprisine' an outwardly flared series of yielding;` sv which normally hold the leup in open condition, as shown in Fig'. l.

.The arms l are Vtoi-med ot' spring);r wires, two arms to a wire, which cross each other beneath the cup 2, and which are soldered or otherwise suitably secured together beneath the cup. The wires or arms 3 follow the linesv et the cup 2 when it is in the open condition, as illustrated in Figs. l and 2.

ythe u mer or o )en end oit the cu 3 2 is sel i cured to the upper ends oit the wires or arms 3 hy being elamped between thev arms and the turned down upper ends 4 thereof, To prevent accidental tearing ot the e-up 2, pads 5 ol' suitable material may be interposed 1between the clamped portions of the upper edge ot the cup 2 and the wires or arms 3 clamping: the same.

The bottom ot the cup 2 which is ot relatively small diameter is made much thicker than the remaining' portions thereof to receive pposingx; indentations 6 formed in the lower ends ot the wires or arms 3, as a means to hold the bottom of the cup 2 in 'pl-:ire within the bottoni of the Page tormed V`bv 'the arms` and to prevent its accidental 'dentetione` G 'compress the bottom oi the cup `and embed themselves therein.

The eupf and the enclosing it formed by the springt arms S Vare adapted to be Collapsed into a relatively smallv space. and, when thus collapsed, to be confined within a suitable casing` 7 ot relatively small dimensions. rllhif-t` casino; 7 may be ot' any suitable shape for its intended purpose, and, as shown in Figs. l and 5, it comprises a tubular body S elosed at its lower end 9 and provided with. a removable cap 8a for closing its upper end,

"When the cup is in the collapsed condition, and confined within the casing 7, as shown in Fig. 4t. the spring arms 3 are held substantially parallel to eaeh other by the walll ot the casing 7 and the body of the cup is held in its folded or .collapsed condition within the easing. When the cup is removed from the casing 7, the spring arms 3,

upon being thereby released, automatically return to their normal condition and thereby automatically return the cup to and ret-ain it in its normal or open condition, as shown in Fig. 1.

As the cup 2 is withdrawn from the casing 7, with its upper or open end foremost, the cup 2 and its spring arms 3 will gradually assume the open condition, due to the fact that the cup 2 and its series of spring arms 3 are outwardly iared. Fig. 5, showing the cup partially withdrawn from the casing 7 shows the cup partly open and returning to its normal condition.

l'Vhen the cup is returned to the casingl 7 the lower or small end of the cup is first inserted into the open end ofthe casing, and, thereafter the cup is pushed down into the casing to the position shown in Fig. l. As the cup is thus pushed into the casing, the flaring spring arms 3 will. engage the casing 7 and be thereby gradually forced toward each other until the cup is entirely collapsed within the casing; and, during this operation, the casing 7 receives and folds inp wardly or collapses the cup body 2.

lt will now be understood that the cup may be readily placed within or removed from the casing, and that, while it is being placed therein, it will be gradually and automatically collapsed by its engagement with the casing, and that while it is being` withdrawn from the casing, it will gradually and automatically assume ,the normal or open condition for use.

One of the spring arms 3 is provided with a projecting handle 10 which may be used to withdraw the cup from and to move it n into the casing; and, after-it has been placed therein the cover 8a may be placed upon the open end of the casing to protect the cup.

" ln the modification shown in Figs. 6 and 7, the cup 11 and casing 12 are the same as shown in Figs. 1 to 5, inclusive, excepting that the handle 10 is omitted and both ends ofthe casing 12 are open and the lower end of the cup 11 and its spring arms are enclosed Vwithin a head'13 which is secured thereto and has an exterior diameter which is substantially equal to or slightly less than the interior diameter of the casing 12, so that the cup may be inserted into the casing through the open `upper end thereof and be withdrawn from the casing through the lower open end thereof, and so that the head 13 will close the lower end of the casing when the cup is confined therein.

l claim as my invention e 1. The combinationof a cup of collapsible material, and a plurality of spring arms connected at the lower ends thereof and embracing the cup and normally holding it in open condition and permitting it to be collapsed under pressure, said arms having indentations in the lower portions thereof engaging the lower portion of the cup and holding it in place'.

2. The combination of a cup of collapsible material, and spring arms embracing the cup and normally holding it in open condition and permitting it to be collapsed under pressure, saidv arms having turned down `upper ends, and the top of the cup being clamped between said arms and the turned down ends thereof. i

3. The combination of a casing having a removable cap, a cup of collapsible material,-

and a series of yielding arms connected to and carried by the cup and adapted to hold it in open condition when the 'cup is unconned, said cup and its arms being adapted to be introduced to and removed from the v,LOUIS SCHORPP.
